Syncretism is the reconciliation or fusion of differing systems of belief.
Syncretism is something that is even present in Western Christianity. But it is often easy for us to see syncretism in other cultures. One of these cultures is in societies that practice animism. How to we present the gospel in animistic societies while avoiding syncretism.
In our culture we tend to think of things individually, but in many other cultures including animistic ones their thinking is very holistic. In the western world when Christianity is taught it often deals with cosmological questions such as; our origin, destiny, and the meaning of life. Many other cultures on the other hand are more concerned with practical everyday issues such as illness, death, drought, financial success, and romance. This results in Christians that follow Christ in the way of cosmological issues but when it comes to the everyday issues they resort to the traditional way of thinking.
This can be avoided by communicating the Bible in a holistic way. Making sure to address the big issues and question of the community. It is also important to make sure that you contextualize the gospel for the culture of the society you are working with. If people have to change their culture for the gospel they are more likely just to change the gospel to suit their culture.
